cube root of 9 Is 2.08 so you minus 15-2.08=12.92
How would you write (a-b)^5 without simplifying it?
The way we can write the expression (a - b)⁵ without simplifying is by using Pascals' Triangle to get; a⁵ + 5a⁴b + 10a³b² + 10a²b³ + 5ab⁴ + b⁵
How to use Pascals' Triangle of binomial coefficients?Pascal’s Triangle is a method that is used to know the binomial coefficients of terms of binomial expression (x + y)ⁿ, where n can be any positive integer and x,y are real numbers.
For the expression (x + y)⁵, the coefficients are;
1, 5, 10, 10, 5, 1
According to the binomial expansion, the power of m will be decreasing while the power of 5 will be increasing as shown below. Thus;
(a - b)⁵ = (a + (-b))⁵ = a⁵ + 5a⁴b + 10a³b² + 10a²b³ + 5ab⁴ + b⁵

Step-by-step explanation:
5y + 5 +6y + 10 = 180 A straight angel is 180 Combine like terms
11y +15 = 180 Subtract 15 from both sides
11y = 165 Divide both sides by 11
y = 15 Substitute 15 in for y
5y + 5
5(15) + 5 = 80
Answer:

The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time, x, measured in seconds. Use the constraints of the real-world situation to predict the height of the water balloon at 15 seconds. Use complete sentences to support your answer.
From the linear model we can see that the height of the balloon after 15 seconds is 0 feet.
Depending on the context, the phrase "linear model" is used differently in statistics.
The word is frequently used interchangeably with a linear regression model since it occurs most frequently in relation to regression models. The phrase has a different connotation when employed in time series analysis, though. The term "linear" is used in each instance to denote a subclass of models for which a significant decrease in the complexity of the underlying statistical theory is feasible.From the linear model we can see that the water balloon is thrown from a height of 40 feet upwards.
Now the balloon reaches a height of 70 feet and then falls back down on earth due to gravity.
At about 10 seconds the balloon falls on the ground and splashes.
Hence for further time the balloon is always at the ground.
Therefore at time of 15 seconds the height of the balloon is always 0 feet as represented in the linear model.

Brown bears attempt to catch salmon. during the day, 20% of the attempts are successful. during the night, 36% of attempts are successful. a bear tries to catch 40 fish during the day and makes 50 attempts at night. use probability to estimate the number of fish the bear caught.
The probability for the number of fish the bear caught is 0.289
Given,
Number of fish the bear tries to catch during day = 40
Number of attempts made by the bear at night = 50
Percentage of successful attempts during day = 20%
Percentage of successful attempts at night = 36%
Number of fish the bear caught during day = 40 × (20/100) = 4 × 2 = 8 fish
Number of fish the bear caught at night = 50 × (36/100) = 36/2 = 18 fish
Total number of fish the bear caught = 8 + 18 = 26 fish
Now,
Probability for the number of fish the bear caught:
Probability = Number of fish caught / Total attempts
Probability = 26 / (40 + 50)
Probability = 26 / 90
Probability = 0.289
Therefore,
The probability for the number of fish the bear caught is 0.289

Answer: y = (5x/4) + 2
Step-by-step explanation:
Answer:
y = 5/4x + 2
Step-by-step explanation:
First, we convert 4x + 5y = 15 to slope intercept form (y=mx+b):
5y = -4x + 15
Divide both sides by five
y = -4/5 (x) + 3
The slope is -4/5
A perpendicular slope is the negative reciprocal of the other line. To find the negative reciprocal, you switch the numerator and denominator and switch the sign.
Slope = 5/4
Plug the slope and (-4, -3) into the slope-intercept form:
-3 = ( 5/4 · -4 ) + b
Isolate b (the y-intercept):
-3 = -5 + b
b = 2
y = 5/4x + 2

The area of a square field is 3.24hectares . Find its perimeter in decimeters
The filed has a perimeter value of 720000 decimeters
How to determine the perimeter of the field?From the question, the area of the field is given as
Area = 3.24 hectares
Also, we have the shape of the field to be square
So, we start by calculating the side length of the field using
Length = √Area
Substitute the known values in the above equation
Length= √3.24 hectares
Length= √3.24 * 10000 square meters
Evaluate the square root
Length= 18000 meters
The perimeter is calculated as
P = 4 * Length
So, we have
P = 4 * 18000 meters

If about 5% of americans have blue eyes, the probability of 3 people selected at random having blue eyes is 1/8000.
About 5% of americans have blue eyes
The probability of a person having blue eyes = 5% = 5/100
Eyes colour of a person is an indepedent event, which means the eye colour of one individual is independent of the other. The probability of one individual having blue eyes or not is independent of another person.
In case of independent event the probability of A intersection B = probability of A multiplied with probability of B
P(A∩B) = P(A) x P(B)
P(A∩B∩C) = P(A) x P(B) x P(C)
The probability that all 3 have blue eyes = 5/100 x 5/100 x 5/100
= 125/1000000

What are the coordinates of the point on the directed line segment from (3,−3) to (7,5) that partitions the segment into a ratio of 5 to 3
The coordinates along the directed line segment is (37/7, 11/7)
How to find the coordinates of the point?The points are given as:
A = (3, -3)
B = (7, 5)
The ratio on the segment can be represented as;
m : n = 4 : 3
So, we have the coordinates of the point that lies along the directed line segment to be
Point = 1/(m + n) * (mx2 + nx1, my2 + ny1)
So, we have:
Point = 1/(4 + 3) * (4 * 7 + 3 * 3, 4 * 5 + 3 * -3)
Evaluate
Point = 1/7 * (37, 11)
Evaluate the products
Point = (37/7, 11/7)
Hence, the coordinates of the point is (37/7, 11/7)
